The **FAS-35-R** is a specialized high-performance fire alarm strobe (typically manufactured by brands like **Mircom** or **Secutron**). It is designed for visual signaling in life safety systems. Below is a breakdown of its electronic components and technical specifications. --- ### 1. Core Electronic Components The FAS-35-R operates using a combination of high-voltage discharge circuitry and synchronization logic. | Component | Function | | :--- | :--- | | **Xenon Flash Tube** | The primary light source that produces a high-intensity white flash. | | **Trigger Transformer** | Steps up the voltage to ionize the gas inside the xenon tube, initiating the flash. | | **Energy Storage Capacitor** | Stores electrical energy from the input line and releases it rapidly to power the strobe. | | **Inverter Circuit** | Converts the low-voltage DC input (typically 24V) into the high voltage required by the capacitor. | | **Synchronization Module** | Ensures multiple strobes in a single area flash at the exact same moment to prevent photosensitive epilepsy triggers. | --- ### 2. Technical Specifications The electronic performance of the FAS-35-R is governed by its power draw and light output. * **Operating Voltage:** Typically 24VDC (Filtered) or FWR (Full Wave Rectified). * **Candela Rating:** This model is usually rated at **35 Candela**, which determines the intensity of the light. * **Mounting:** Designed for wall-mount applications (indicated by the "R" often referring to Red housing). * **Polarization:** The unit is electronically polarized for use with supervised fire alarm circuits. --- ### 3. Wiring and Integration The FAS-35-R uses a standard 2-wire terminal block system for integration into a Fire Alarm Control Panel (FACP). ```mermaid graph LR A[FACP 24VDC Output] --> B[FAS-35-R Positive Input] A[FACP Ground] --> C[FAS-35-R Negative Input] C --> D[Next Device/End of Line Resistor] ``` ### 4. Key Features 1. **Low Current Draw:** Optimized electronic design to allow more devices on a single Notification Appliance Circuit (NAC). 2. **Stable Flash Rate:** Maintains a consistent 1Hz (60 flashes per minute) as required by NFPA 72. 3. **Supervised Circuitry:** Includes a bypass diode to allow the fire panel to check for "open circuit" faults when the system is in standby. ---
